What fertigation actually is

The no-fluff explanation. And what it isn't.

What we've seen in hundreds of facilities

The patterns that quietly compound into expensive problems.

03

The five core components

The building blocks — and where they fail at the seams.

Water comes first

Why pH and EC aren't the whole story. Not even close.

05

Batch tanks vs direct injection

The real-world tradeoff, and what we install when we get to choose.

Piping design

The most overlooked variable in fertigation — and the math that proves it.

07

Precision & the pump

Why we don't compromise on the dosing hardware.

08

Automation, monitoring & alerts

How automation should feel like support, not stress.

Maintenance & long-term reliability

The unsexy rhythm that separates systems that last.

11

Cost, ROI & sustainability

Final thoughts

Systems that work with you, not against you.

From Nik · Founder & President
"A great fertigation system shouldn't feel like a stack of equipment. It should act like one living thing — treating every gallon of water the same way, mixing nutrients on target, and sending the same feed to every plant, every cycle."
Nik McCalligan · Eden Water Tech
Who wrote this

Real people. Real facilities.

Nik McCalligan

Nik McCalligan

Founder & President

Founded Eden after years of installing other people's fertigation systems and watching them fall short of what they promised. Still spends most days in facilities — sizing rooms, talking to growers, and making sure the systems we ship behave the way the spec sheet says they will.
